To agllwhom it may concern;

Be it known that I, ERNST ZILLESSEN, a subject of the German Emperor, residing at Passaic, New Jersey, have invented certain new and useful Improvements in Dyeing A paratus, of which'the following is a clear, full, and exact description.

The object of this invention is to provide apparatus for dyeing which -will be economical in theuse of dyeing solution and dyestuff and give to the cloth the proper shade and luster, with ease of manipulation of both cloth and dye-bath. I

In carrying out this invention I rovide a plurality of trays, preferably shal ow pans, and I lead the cloth first through one tra and then another. The trays are filled wit a dyeing solution, preferably from a circulating system comprising piping and a suitable pump. The trays may dye-bath in any suitable way; ut I prefer to feed each one separatelyfrom a common suply-pipe and to provide a separate overflow em each tray or pan to the circulating means I preferably provide each an with a dam, which may be an ordinary ba e-plate, to maintain the level of the-bath. Each tray is preferably supplied with rollers or guides to hold the fabric off the 'fioor of the tray. Rollers may be supplied for s ueezing out the surplus dye-bath from the fa ric as it comes from each tray. T ensioning-rollers may be supplied for keeping the cloth taut within the trays, and preferably they will be so'sha ed as to give a sidewise stretch to the materia as it passes over them to keep the cloth fiat. To economize in room, I refer to superpose the trays and preferably eed the dyestuif to each tray from a common supplypipe by individual pipes. When the feeding system is a circulating one, I use a pumping means for keeping up the circulation. In order to keep up the required density of the dye-bath, I from time to time insert concentrated dyestuif into the system, preferabl before the bath has reached the pump, set at the feedpump may thoroughly mix it into the bath. As will be obvious rom the claims, my invention is not limited to that embodiment illustrated in the drawings or specifically described hereinafter; but the constructions and arrangements may be varied without departing from my invention as set forth in said claims. I

In the drawings, which show the preferred form of'my invention, Figure 1 is a sectional be supplied with the diagrammatic view of vention, and Fig. 2 is a the stretchin -rollers.

apparatus of my inetail view of one of In my pre erred construction the trays 3 are superposed one above another above a receiving-tank 1 and at a lower level than a feed-tank 2. The tanks 1 and 2 are connected by pipes 13 and 14, which are themselves joined by a pump 9. From the tank 2 I lead referably a sin le feed-pi e 1.5 and tap off om it at suita le interva s withpi es 16, each adjacent pipe 16 preferably leading to opposite ends of adjacent trays. Each tray 3 is preferably providedwith a dam or bafiieplate 4 near one end, preferably at the end opposite the inlet of the pipe 16, near which plate 4 an outlet-pipe 181s located, which connects with a pipe or pipes 17, adapted to lead their contents to the receiving-tank 1.

Guide-rollers 5 are located within the trays to support and hold the fabric off the bottom or tray floor, while squeezing-rollers 6 (which I prefer to also use to draw the cloth through the trays) are located at one end of-ea'ch tray to expressthe surplus dye solution from the cloth as it emerges from the tray. A roller 19 may be located at the end ofthe tray opposite the squeezing-roller, if desired.

At a convenient point adjacent to the ends of two trays I preferably locate a tensioningroller 7, preferably formed, as shown in'Fig. 2, with a reverse helical surface. A spring 8 or other tensioning means may be attached to said roller to give a longitudinal tension to the cloth 20, while the peculiar form of-the surface serves to keep it spread sidewise by imparting a sidewise pushing effect from the center to the cloth.

At a convenient point within the circulating system of pipes and tanks I prefer to locate a means for inserting dyestuff into the dye-bath. I prefer to select the pipe 13 as this point and to lead the dyestufi by a pipe 12,,having a valve 11 leading from a container 10, holding highly-concentrated dyestuff in the li uid form; but such liquid form and the speci 0 means for inserting the dyestuif may not be essential. By inserting it at the point indicated the feed-pum 9 acts also as a mixin means for thorough y mixing it in the dyeath.

In operation I first supply suflicient dyebath in quantity and density to the trays and tanks and then pass one end of a roll of cloth successively through the trays in the following course, first over roller 19 of the lower- IIO most tray, then under roller 5 at the left of the tray, over the central roller 5 at the left of the tray, over the central roller 5 and under the right-hand roller 5, then to the squeezing-rollers, and then over the tensionroller 7 to the roller 19 of the next higher tray, through which the cloth passes in reverse direction of travel. The direction is therefore changed as the cloth passes through adjacent trays, which trays in the exam le shown herein receive the dye-bath at the end opposite to the entry of the cloth.

I claim as my invention 1. Apparatus for dyeing comprising a series of relatively shallow open superposed dyeing-trays and means for passing a piece of cloth successively through the trays of the series, and means for supplying dyeing liquid to the trays.

2. Apparatus for dyeing comprising a se ries of open superposed dyeing-trays and means for passing a piece of cloth successively through the trays of the series, in combination with means for continuously circulating dyein liquid through the trays.

3. pparatus for dyeing comprising a series of open superposed dyeing-trays and means for assing a piece of cloth successively through the trays of the series, in combination with means for continuously circulating dyeing liquid through the trays and means for inserting dyestuff in the circulating dyeing liquid.

4. Apparatus for dyeing comprising a series of open superposed dyeing-trays and means for passing a piece of cloth successively through the trays of the series, means for circulating dye liquid comprising a pump, and means for inserting dyeing material comprising piping leading to the circulating system on t at side of the pump from which the liquid is fed to it.

5.. An apparatus for dyeing comprising a plurality of open superposed dyeing-trays, means for passing the cloth successively through said trays, and means for feeding the dyeing liquid to each tray independently of the others and an outlet from each tray.

' 6. Apparatus for dyeing comprising a plurality of superposed dyeing-trays, means for feeding the dyeing liquid through the trays and means for passing the cloth successively through the trays in combination with a continuous circulating system for the dye-bath.

7.

13. Dyeing apparatus comprising a number of trays, and means for passing cloth through the trays successively, means for stretching the cloth lengthwise and sidewise as it is passed therethrough, in combination with means for continuously passing a dyeing liquid through said trays.

14. Dyeing apparatus comprising a number of trays, means for passing cloth through the trays successively, in combination with supply-piping and a pump for continuous circulating dyeing liquid through the trays, and means for inserting dyestuil' into the liquid as it comes from the pans whereby the same dye-bath may be used indefinitely.
